l SPECIFICATION forming part of VLetters Patent No. 539,784, dated May28, 1895.

. Application led T une 16., 1894:.

.To all whom it may concern! Beit known that I, HENRY W. AUBREY, acitizen of the United States, residing at Sunset, in the county ofMontague and State of Texas, have invented a new and useful'Cultivator,of which the following is a specification.

My invention relates to that class of cultivators wherein the frame andits attachments are mounted upon carrying-wheels and the plows made todepend therefrom; and the principal feature of the invention consists ofcertain specific improvements in the construction of the frame, wherebyitis made to operate with greater ease, and whereby its durability andcheapness are increased.

In the drawings, Figure 1 represents a perspectiveview of my completeinvention; Figak 2, a longitudinal section; Fig. 3, a cross-sectiontaken through the coupling-beam; Fig. 4, a detail perspective ofthejoint whereby the plows are connected to the frame; Fig. 5, a detailperspective of the rear end of the cultivator; Eig. 6, a detail viewshowing the 4devices for securing the plow-beams to the main beams. v

The reference numerals 1 indicate thetwo main or draft beams of mymachine, and these extend longitudinally and parallel, and are eachprovided with the two upwardly and inwardly extending beams-2 and 3,which 4are secured to the upper side of the draft beams 1 by means ofthe metallic plates 4, bolted to the several parts, as shown. The'upperends ofthe beams 2 and 3 are located a short distance apart and rigidlysecured to each other by means of thel plates 5, secured one to eachside of the beams, and extending from one to another.

Secured to the rear ends of the draft beams 1, and embracing the beams3p, which are just above it, and projecting downwardly from the beams,are the arms 6, which extend parallel with each other, and may be formedof an integral piece of metal, or of separate pieces, as preferred.Journaledin the lower and opposite ends ofthe plates 6 are thecarrying-wheels 7.

Located in the space left between the ends of the beams 2 and 3, andbetween the two brace plates 5, are the sliding beams 8, which areadapted to fit snugly within their respectsans No. 514,782. (No man.)

ive spaces. These beams 8 are capable of a vertical movementin theirseats andthis is limited, and the beams prevented from moving out oftheir places by means of the enlargements or heads 9, which. arelocatedone at each end ofthe beams, and which are of a size that will make themincapable of passing the spaces in which the beams 8 are seated.

Formed in the heads, which are at the upper ends of the beams 8 are theopeningslO, which extend laterally and are so located that they willlieabove the plates 5 when the arms 8 have moved as far down as the upperVopenings 12, the beams 8, and consequently j the two sections of thecultivator, may be moved toward and from each other-and held at anyposition within the scope of their movements.

. The ends of the rod 1l are bentdownwardly to form studs 31, which arepassed through openings in the links lla, whereby vthe parts arepivotally connected.` By this construction, the sections are connectedsoas to be capable of transverse adjustment, and of a limited independentmovement longitudinally and vertically on -the links 1la and beams 8respectively. A

Rigidly secured to the forward ends of each of the draft beams 1, arethe stoutv arms 15,

which project out from both sides of their re' spectivebeams, and areprovided with vertically disposed passages 16, through which the pins 17pass. The pins 17 are provided to hold the beams 18 in place. Thisconnection between the beams 18 and 1 is effected by bif furcating theforward ends of thebeams 18, so as to form jaws 19 which are adapted tolie one on each side of the arms 15, and to receive the pins 17.

The beams 18 extend rearwardly to a point just forward of the rear endsof the beam 1,

and, on each side thereof, and have their reary ends formed with thevertical shoulders 20, communicating with the forwardly-inclined faces21. Pivoted to the rear ends of the beams 18, and one on each sidethereof, are the plates 22, which extend normally rearwardly and arerigidly secured to the bealns 23. These beams 23 are one for each of thebeams 18 and form continuations thereof, they being joined thereto asdescribed, so that they will be capable of swinging upwardlyr on thebeams 18, but will be incapable of downward movement owing toshoulders20.

Those plates 22, which are arranged on the inner sides ofthe beams 23,extend to the rear extremities thereof, while the outer plates projectbeyond the rear ends of the beams and bend inwardly, parallel with therear sides of the brace beams 24, to which rear sides they are securelyfastened by bolting or otherwise. Braces 24 are formed with their endsbifurcated horizontally, through which bifurcations the outer plates 22pass.

In addition to the plates 22 the standards 25 are passed through thebifurcations of the braces 24. The standards 25 curve downwardly, andthence forwardly from the beams 23, to which they are rigidly attachedby means of the bolts 26.

The lower ends of the standards 25 are formed with seats 27 on which thecultivator blades 28 are secured by bolts 29 passing through them andthrough the beams.

Securedto the braces 24, and" projecting rearwardly therefrom, are thearms 30, which extend upwardly and rearwardly to a point beyond thecultivator blades 28, and by which such blades may be raised or lowered.It will be seen that the blades of each beam 1 may be raised by swingingthe beams 23 on the beams 18, and this is facilitated and rendered easyby the arms 30.

Secured to the forward ends of the beams 1 are the clevises 31, whichare one for each beam and adapted to have the whiflletrees 32 securedthereto. By these means the machine is attached to the team for drawingit.

In the use of my invention, the team is attached to the machine, and thelatter drawn through the field to be cultivated; the cultivator-blades28 having been first lowered into engagement with the ground. This willresult in the plowing of the ground, all of which is well understood.

By means of the vertically-movable beam 8, the two sections of thecultivator are connected so as to be capable of independent verticalmovement, thereby allowing one of the sections to move, under theiniluence of any unevenness in the surface of the ground, irrespectiveof the remaining section, and taking the strain off rod 11, which strainwould otherwise attend it.

Having described my invention, what I claim is- 1. The combination withtwo similarly-constructed cultivator sections, each section comprising adraft beam having a supporting wheel at its rear end, andoppositely-inclined braces formed with a vertical space between theiropposing ends, a vertical beam resting upon the draft beam between itsends and operatin g in the said vertical space, of a transverseconnection adjustably uniting the upper vends of the vertical beams ofthe two cultivator sections, and cultivator beams having suitableconnection with the forward end portions of the aforesaid draft beams,substantially as described.

2. In a cultivator, the combination with a draft beam having asupporting wheel at its rear end, of cultivator beams pivotally attachedto the forward portion of the said draft beam so as to swing laterallyoutward at their rear ends, and standards having pivotal connectionkwith the rear ends of the cultivatory beams so as to swing upward, andhaving a limited downward movement, and having cultivator shovels attheir lower ends to operate in the rear of the said supporting wheel,substantially as set forth.

3. In a cultivator, the combination of a main beam 1 provided withsuitable draft apparatus, two beams 18 pivoted one to each side thereofand capable of swinging horizontally thereon, plates 22 pivotallymounted one on each side of the beams 18, beams 23 securely fastened oneto each pair of plates 22, whereby beams 23 are made capable of swingingvertically on the beams 18, a brace 24 rigidly secured' to the rear endsof the beams 23 by securing two of the plates 22 to it, andcurvedstandards 25 rigidly secured one to each of the beams 23 andl projectingrearwardly therefrom, the standards 25 being adapted to carryplow-blades and being passed through notches or bifurcations in therespective ends ofl the brace 24, substantially as described.

4. The combination with two similarly-constructed cultivator sections,each section comprising a draft beam having a supporting wheel at itsrear end, and oppositely-inclined braces formed with alvertical spacebetween their opposing ends, and a vertical beam resting upon the draftbeam between the ends of the latter and operating in the said Verticalspace, and having a transverse opening in its upper end, of linksadjustably held in the said transverse openings of the vertical beams,and a rod having its ends bent and forming pivotal connection with theinner ends of the said links to connect them and the two cultivatorsections, substantially in the manner set forth for the purposespecified.
